YORKSHIRE BUILDING society has been fined £4.1 million on top of the £8.4m it is already paying to compensate mortgage customers who were poorly treated when they got into difficulties.

The Financial Conduct Authority said delays in determining the most suitable repayment plans resulted in some customers incurring increased mortgage fees and associated interest.

The Bradford-based lender has already started the process of refunding 34,000 customers an average of £247 for fees and accrued interest charged since 2009.
